To all whom it may concern Be it known that I, WILLIAM C. Roorr, acitizen of the United States of America, residing at Upper Sandusky, inthe county of Wyandot and State-of Ohio, have invented new and usefulImprovements in Igniters', of which the following is a specification.

This invention relates to improvements in igniters for internalcombustion engines and has particular application to anigniter of theflame heated type. p

In carrying out the presentyinvention, it purpose to provide an ignitingdevice which will be carried by the cylinder head and extend into thesame in'the path of the incoming live fuel so that the'latter will beignited to propel'the engine piston.

It is also my purpose to provide an igniter instance, of a'hollowcylindrical body 9 havwhich may be initially heatedin a relatively shorttime and which will embrace the desired features of simplicity,efliciency and durability. j

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claim.

In the accompanying drawing; Figure 1 is a fragmentary side elevation ofa horizontal cylinder stationary engine equipped with an igniterconstructed in accordance with the present invention, part of thecylinder being shown in longitudinal section. Fig. 2 is an enlargedlongitudinal sectional View through the igniter.

In the present instance, I have shown my invention as applied to a twocycle internal combustion engine of the stationary type. I wish it to beunderstood, however, that my invention in its useful application is notlimcommunication between the latter and the crank case of the engine,the piston in its rearward movement compressing the air cylinder.

From the foregoing description taken in connection with the theconstruction, manner of employing my invention will be Vvhen it isdesired to initially heat the igniter, a torch or the like attheopposite side,

In the operationof the engine, air under pressure is delivered to the engine cylinderthrough the passage 5, when the latter is uncovered by the piston, andthe piston in its forward movement compresses such air to a high degree.When the air is thus under compression, the fuel is delivered into thecylinder by the inlet nozzle 7 and impinges upon the body of theigniter, incident to the latter being in the path of the fuel, such fuelbeing thereby vaporized and commingles freely with the compressed air soas to form a highly explosive mixture which is fired or exploded by theheat from the igniter and the adjacent walls of the cylinder head inaddition to the heat of compression. The gases, exploding, drive thepiston inwardly on the power stroke, the power being taken from thepiston through the agency of a pitman and crank shaft or in some othersuitable manner, as is readily apparent to those skilled in the art.When the piston reaches its limit of inward movement, the exhaust port 6is uncovered so that the burnt gases escape to the atmosphere, while thepassage 5 is also uncovered to deliver a fresh charge of air to thecylinder at which time the above operation is repeated.

It will be seen that I have provided an igniter by means of which theoil entering the cylinder is thoroughly vaporized and subsequently mixedwith the air under coin- Copies of this patent may be obtained for fivecents each, by addressing 'ginal edge of said outer end of said body,

While I have herein shown and described one preferred form of myinvention by way of illustration, I desire to have it understood that Ido not limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claim without departing from the spirit ofthe invention.

1 claim:

An igniter for internal combustion engines comprising a cylindrical bodyprojecting into the cylinder of the engine in the path of the gases, apartition arranged within said body centrally thereof and terminatingshort of the inner end of the body whereby communicating longitudinalchambers are formed, a circumferentially extending flange formed on theouter end of said body, a cup-shaped cap secured to the marfiange andclosing the said cap being formed with an inlet openmg at one side ofthe partition and an outlet opening at the opposite side of suchpartition.

In testimony whereof I affix my signature in presence of two witnesses.
